    Revenge from Mars monitor problem

    Hello Arcade Professors,

    Sorry for doing this in English but my German is not that good
    I have a problem please help me if you can.

    I bought an revenge from Mars pinball with a non working monitor.
    I didn't know if it was the pc or the monitor so I hooked it up an other monitor to see what would happen.

    I got a picture so I think the pc is oké.
    Problem is the picture is not correct. It's like the picture won't get to the middle and the writing is double. Tried to get a good picture by using the monitor adjustment buttons but that won't solve it, believe me I tried :/ .

    Picture of the connectors:
    Left the original pinball 2000 cable/plug right the "new" tatung monitor cable/plug from a magatouch xl.
    Original plug: pin1: orange pin2: beige. Pin3: back and yellow. Pin 4: black pin5,6 empty. Pin7 pink Pin8 black pin9 green. Pin10 brown.
    New plug: pin1 yellow. Pin2 white. Pin3 black. Pin4 black. Pin5 blue. Pin6 black. Pin7 white. Pin8 black. Pin9 pink.
    I tried to connect the pinball 2000 plug to the new cable and swapped some cables around but nothing seem to work.Maybe it just not working with this monitor but since it looks so close I'm hoping its some kind of sync problem.

    Please help me, I tried to look up the answer on the net but that kind of drove me crazy.
    Thanks in advance.

    Greetings, Arlon Weijer.

    HI
    First at all: Pin2000 is lowres, you need a "normal" 15K arcade-monitor. With 48cm CRT.
    The megatouch ist VGA, i think so. Your faulty picture looks like wrong resolution!
    And the sync signal from your PC is other polarity as "normal" arcade use. Also it comes with separate sync for H and V!!!

    The original connector looks like Wells Gardner standard.
    What monitor do you have origin in your pin?
    Wells Gardner or Ducksan? This two manufactors were used.....

    Why do you try to swap the monitor? Is the CRT broken? Or simply the chassis faulty?
    However, a dead chassis should not be any prob for me, also i would be able to assist you fixing it.
    Little knowledge of soldering and measurement is important.

    Regards from germany

    Hi Winfried,

    Thank you a lot for your response !
    Spent hours trying tho get the Megatouch getting to work 🙄
    The original monitor is a Wels Gardner but is totally dead just black screen.
    I'm not an electronic expert but I can do some electric work.
    I tried wiggling the neck board but no glow in the neck.
    Would be awesome if you could help me out but like I said I'm not an expert, and I not really know where to start.
    I will send you some pics of the monitor later.
    Thanks in advance.

    HI
    Can you read and interpret the circuit-diagram?
    Is the 115V power supply present? I think so, cause the computer works and thats the same power circuit.
    Blown fuse on the monitor-board?
    Next point of measurement schould be the mains capacitor, 160V or more has to be there
    Did you have had a look at the soldering under the PCB?
    Broken joints etc are suspect...
    Regards
    Winfried

    I looked at the capacitors and some of them have some brown stuf under them.
    they are not swollen up maybe the brown stuf is just soldering fluid.
    wanna try putting on new capacitors my self but not sure if that's wise.
    if I wanna do it myself where do you recommend me buying new capacitors?
    is it possible sending you the neck board and the other pcb board so you can check them and repair them if you think that's possible?
    is you want to do this can you give me an indication of how much this gonna cost me?
    thanks for the info you gave me till now

    HI
    You are on the "woodway", so we say in Germany, meens, you are looking at the wrong place....and on the wrong way!
    The caps look fine, and the yellow "slime" is only the (factory)glue to keep them in place due to vibrations.
    If you mean that your not able to fix it by yourself, its no prob for me to do the job.
    i have the skills and the spareparts to get it along. The fee for fixing depends on the dufficult of the fault, however.
    Maybe between 20 und 200 €...., really i think its in the house number of 50 bucks plus postage.
    Feel free to get information about me, and my knowledge........i.m a well known tech in Germany

    Regards
    Winfried

    Sending a complete monitor is like russian roulette.....i need the chassis incl. neckboard and the adjustment-pcb.
    The CRT and wiring remains at your home. I m in need for only the complete electronic to drive the CRT.
    CRT and all other equipment is no prob here.

    Hoi,
    im gonna sent you the boards.
    thank you for wanted to do this.
    the problem is my budget for my pinball hobby is very low at the moment
    so please let me know if it's going to cost more than €60,--
    really hoping it is something wrong with the boards and not with the tube it self.
    on the picture I am pointing on the 7 round things at the neck of the tube they are lose I can move them eazely is this normal do they have to be in sertan positions?
    i am confidant that you can fix it if it is something wrong with the boards, please keep me informed about the progress.
    pleas sent me your complete address.
    thanks again !!

    HI
    These rings are factory adjusted and sealed with locking paint.
    In the normal way they are fixed in most certainly position.
    As an amateur you never will be able to do these settings, even with test pattern (your pin2000 has that in the testmenü) you will get crazy!
    Look at the painting so you can reconstruct them. Than fix it.
    If you cannot find the original settings, your crt will give you a faulty picture.
    The colors will be poor and the convergency wrong and bad.

    For example look here, page 5 und so on!
    http://www.wellsgardner.com/pdf/Service/K7000.pdf

    When youre able to reseat the magnetic rings in the origin position, then there is good hope to get it at work fine.
    Otherwise you have to send the whole equipment..........but this will generate very more costs ... :-(
    Try to fix it, there are six rings and the seventh ring will lock and unlock them all, i think.
    If you are not able to do this, the sending and repairing of the chassis would be wasted money!

    Sorry, but thats the fact and i dont want to do the job in vain. Only collecting your money.....and sending any useless stuff to you.

    Friedly regards
    Winfried

    Someone did put a line on there with a marker.
    if I line the marks up it look like in the picture.
    say this is all wrong, is it possible to use the tube from the Megatouch xl with the boards of the pinball 2000 ?

    You probably know a thing or 2 about conversion kits.
    maybe it is just easier for me to go that route I know I would not get a better picture with a TFT monitor but better not a perfect picture than no picture at all.
    i bought a gbs 8200 and build a input withs should work, but than I read on the internet that some of these gbs 8200 things just are not working.
    a conversion to a TFT screen in a pinball 2000 is just not a plug and play job.
    can you like sell me a converter system that would work in a pinball 2000 machine ?

    HI
    The marked line shows you the adjustment, that looks good.
    When you get them fixed in this way, the tube should work.
    This is no promise from me, finally the firing up with the chassis can give you the answer.
    The disjusted rings cannot cause the dead of the chassis.
    There is not any device you can use from your megatouch, it is VGA-resolution and works in different way.
    The inductances of the deflection coils ars total different.


    The TFT-solution is not my business, sorry.

    You can send the chassis to me and i will it bring alive.
    When you get it back und your crt is bad, you can send it to me and i will keep it for the repair cost.
    So you cannot invest in food for a dead animal

    regards
    Winfried
